Effects Of Landing Strategies On Lower Extremity Sagittal Plane Kinetics And Kinematics

Context: Landing with higher quadriceps contraction demands (i.e. knee extensor moment production demand), and lower hamstring contraction demands (i.e. hip extensor moment production demand), and higher ground reaction forces may increase the risk of non-contact Anterior Cruciate Ligament (ACL) injury, especially in conjunction with shallow knee flexion angles. Changing landing strategies may alter lower extremity biomechanics, possibly influencing ACL injury risk. Objective: To examine how different landing strategies influence lower extremity sagittal plane kinetics and kinematics.
